2 Transformer s Transformer loads sometimes result in severe inrush current when the transformer saturates during the rst cycle. Use a relay rated for this surge, which has a 1/2 cycle surge current greater than the maximum applied line voltage the transformer s primary resistance (approximately 10x rated current).

In such cases, use an SSR relay at no more than 75% of the rating.

At 4V input, the relay will turn on with 3mA: [4V (1V drop across LED) = 3V]; [3V 1,000Ω = 3mA].

Read the following technical notes prior to installing then quality solid state relays.

3 Technical Notes Environment Do not install SSRs near sources of excessive heat. Make sure applications are dry and well ventilated. If SSRs must be installed in an environment subject to high temperatures or poor ventilation, or if SSRs are mounted collectively, reduce the load current so that it does not approach the ambient temperature-load current recommendation. (See the Temperature Derating Curves on the following page.) When SSRs are used with inductive loads, suppress the inrush current to half of the peak surge current. Heat Sinks Heat sinks are recommended for 10, 25, 50, 75, and 90 amp rated solid state relays depending on ambient temperature and mounting position. The recommended heat sink dimensions and material are shown in the table: Rating Dimensions Material 10A 12" x 12" x 1/8" Aluminum (black anodized) 25A 12" x 12" x 1/8" (DC/AC) Aluminum (black anodized) 25A 15" x 15" x 1/8" (AC/AC) Aluminum (black anodized) 50A 15" x 15" x 1/8" Aluminum (black anodized) 75A 17" x 17" x 1/8" Aluminum (black anodized) 90A 17" x 17" x 1/8" Aluminum (black anodized) Using a thermal compound between the base of the SSR and the heat sink for heat dissipation is recommended. Wiring Locate SSRs as far from motor leads as possible to prevent malfunction from induced current. Use shielded wires for input leads when they are exposed to a source of induced current. Mounting Provide sufcient ventilation. Use #6 32 screws, at washers, and lock washers to secure mounting on heat sinks. Vertical mounting is recommended to allow air to ow unimpeded. Horizontal or inverted mounting is possible, but the SSR must be derated according to the derating curves on the following page. Additional Information Do not exceed the load voltage and current specications. A small-capacity load may not turn off due to the leackage current present after the SSR has turned off. If this is the case, use a resistor in parallel with the load to shunt the leakage current. Observe the polarity of input terminals. Failure to do so may cause damage to the SSR. When the SSR output is subjected to a higher than rated voltage, a varistor or other element should be connected to the output terminals to absorb the overvoltage. When the input signal contains a ripple voltage, the lowest ripple amplitude should exceed the minimum pick-up voltage of 4V. Over 4V 0V Lowest Voltage
